SPRINGFIELD - Follow-up samples collected in the Illinois River last week showed no evidence of the algal toxin, microcystin, including samples collected near Hennepin and Marseilles. Previous samples collected at these locations detected microcystins above the 4 parts per billion (ppb) draft health advisory established by U.S. EPA. It is likely that heavy rains received in northern Illinois contributed to the improved conditions in the river.
SPRINGFIELD - Following sampling on the Illinois River, Illinois officials have confirmed the presence of the algal toxin, microcystin, above the 4 parts per billion (ppb) health advisory established by U.S. EPA. An initial screening test conducted on a water sample taken last week near Hennepin indicated an elevated level of microcystin. The Illinois EPA's lab confirmed the microcystin level in the sample at 182 ppb; well above the health advisory limit. The confirmatory sample taken near Marseilles detected microcystin at 4.75 ppb, just slightly above the health advisory limit. Illinois EPA will conduct additional sampling this week to determine if conditions have improved along the Illinois River.
SPRINGFIELD - Illinois officials have been alerted to a possible algal bloom on the Illinois River and are actively monitoring conditions to keep communities and residents informed. Illinois residents are advised to use caution while recreating in, on, or near Illinois rivers, lakes and streams as blue-green algae may bloom in these waters. Some blue-green algae can produce toxins that are harmful to humans and animals. Blue-green algae (also known as a cyanobacteria) are microscopic organisms that naturally occur in lakes and streams.
